What is the purpose of a roundabout?

The purpose of a roundabout is primarily to improve traffic flow and reduce accidents. Roundabouts are designed to keep vehicles moving in a circular pattern around a central island, which helps to maintain a continuous flow of traffic. This design minimizes the need for vehicles to stop completely, reducing the likelihood of rear-end collisions that often occur at traditional stop signs or traffic signals.

Moreover, because vehicles yield to traffic already in the roundabout, there are fewer conflict points compared to conventional intersections, making accidents less likely. The layout also encourages lower speeds, which can reduce the severity of any collisions that do occur. Overall, roundabouts effectively facilitate efficient traffic movement and enhance safety for both vehicles and pedestrians.
